WILLIAM K. PARKER, OF CAMBRIDGE, MASSACHUSETTS, ASSIGNOR OF ONE` HALF TO JOHN H. SULLIVAN, OF BOSTON, MASSACHUSETTS.

VUPHOLSTERY-SPRING.

SPECIFICATION forming part of Letters Patent No. 728,496, dated May 19, 1903. Application filed AJanuary 2, 1903. Serial No. 137,403. (No model.)

To a/ZZ whom/ it may concern:

Be it known that I, WILLIAM K. PARKER, a

citizen of the United States, residing at Cambridge, in the'county of Middlesex and State of Massachusetts, haveinvented new and useful Improvements in Upholstery-Springs, of

y which the following is a specification.

the other of said wires. l

The invention again consists in the instrunlentalities hereinbefore set forth, the free ends of each of said wires extending diagonally across the free ends of the other of said wires.

The invention finally consists in the combination and arrangement of parts setforth in the following specification and particularly pointed out in the claims thereof.

Referring to the drawings, Figure lis a plan view of a spring constructed in accordance with my invention. Fig. 2 is a side elevation of the form of spring illustrated in Fig. 1. Fig. 3 is a plan view of a modified form of spring. Fig. 4 is a side elevation of the spring illustrated in Fig. 3. Fig. 5 is a plan view of another modified form of spring embodying my invention. Fig. 6 is a section taken on line 6 6 of Fig. 5 looking toward Athe left in Fig. 7 is a plan view of a modified form of spring embodying my invention, in which the terminals of the free ends of the wires are bent at an angle to the main portion thereof and coiled to form spiral-spring supports. Fig. 8 is a side elevation of the form of spring shown in Fig. 7.

Like numerals refer to like parts through-` out the several views of the drawings.

'In the drawings, lO and 11, Figs. l and 2, are the wires from which my improved spring is constructed. The wires 10 and 11 are bent between the free ends thereof to form ties 12l ports being adapted to be fastened to any deand`13, respectively. The tie 12 engages and ties together the free ends 14 and 15 of the wire 1l. The tie 13 engages kand ties together the free ends 16 and 17 of the wire 10. The terminals 18 and 19 ofthe wire 10, and 20 and 21 of the Vwire 11 are bent downwardly, as shown in Fig. 2, to form supports, said supsirable form of base.

y -In Fig. 1 it will be noted that the free ends 14 and l5 are twisted around each other and the free ends 16 and 17 are also twisted around each other and that said free ends 14 and 15 extend diagonally across and beneath the free ends 16 and 17, thus forming a support for said free ends.

In Figs.l3 and 4 the wires 22 23 are bent to form ties 24 and 25, respectively, said ties engaging the free endsof the opposite wire, as hereinbefore described, the free ends of said wires extending diagonally across each other, the terminals of said free ends bent at an an-` gle to the main portion thereof to form supports, as at 26 27, respectively, and thence extended and joined together at 28.

In Fig. 5 a modified form of my invention is illustrated in which the wires 29 30 are bent between their free ends to form ties 31 32. The wires of the terminals 33 34 are twisted around each other,as illustrated'in Fig. 6, and bent outwardly, as at 35, to'forin a support. The yties 3l and 32, Fig. 5, are connected by a spiral spring 36 for the purpose of adding to the strength and resiliency 'of the structure as a whole.

In Figs. 7 and 3 I have illustrated a modiiied form of my invention in which the free ends of the wires 14, 15, 16, and 17are bent at an angle to the main portion thereof and coiled to form spiral-sprin g supports therefor.

From the diifereut forms hereiubefore described, and illustrated inthe drawings, it will be seen and understood that the wires of whichthe spring `as a whole is constructed may be bent in a variety of' shapes to form the ties 12 and 13 and the terminals 18, 19, 20, and 21 without departingfrom the spirit of my invention. I therefore do not wish to be understood as limiting myself to the loo exact shape and construction described and illustrated; but

What I do claim, and desire to secure by Letters Patent, is

l. As an article of manufacture, an upholstery-spring comprising two wires, each of said wires bent between the tree ends thereof to form a tie which engages and ties together the two free ends of the other of said wires.

2. As an article of manufacture, an upholstery-spring comprising two wires, each of said wires bent between the free ends thereof to form a tie which engages and ties together the two free ends of the other of said wires, the free ends of one of said wires extending diagonally across the free ends of the other 0f said wires.

3. As an article of manufacture, an upholstery-spring comprising two wires, each of said wires bent between the free ends thereof to form a tie which engages and ties together the two free ends of the other of said wires, the terminals of said free ends each bent at an angle to the main portion thereof to form supports therefor.

4. As an article of manufacture, an up-y holstery-spring comprising two wires, each of said wires bent between the free ends thereof to form a tie which engages and ties together the two free ends of the other of said wires, the terminals of said free ends each bent at an angle to the main portion thereof and coiled to form spiral-spring supports therefor.

5. As an article of manufacture, an'upholstery-spring comprising two wires, each of said wires bent between the free ends thereof to form a tie which engages and ties together the two free ends of the other of said wires, and a spiral spring fastened at its opposite ends to said ties. I

In testimony whereof I have hereunto set my hand in presence ot' two subscribing witnesses.

WILLIAM K. PARKER.
